Motherboard will not restart

Hi everyone,long time no see.
I bought a new Syntax SV266A motherboard some time back and finally installed it in a new box the other day. From the beginning the motherboard wont restart when ctrl+alt+del is hit. The screen goes black and nothing else happens until I hold the power button in and shut down the system. Even after Windows was installed the same thing happens when Windows attempts to restart the system. With the exception of this problem, the system works fine. Is there any way of fixing this? Or am I stuck with this problem?

 

Hi Blufx,
If it is like my old Asus motherboard, then it will take a BIOS upgrade to fix the problem. I upgraded the BIOS several times, but it was not fixed until some of the later upgrades were available. If you have not flashed a BIOS before, follow the instructions carefully (eg. make certain it for your board's model and revision). Use the floppy method rather than flashing through Windows.

In the mean-time, if it has a reset button, use that when the drive activity has stopped.

Thanks Matt,I'll try the bios update but I don't think that's going fix it. I bought a SV266A combo with a 2 gig AMD processor which is what I've been using for a couple of years now. The first one worked fine and still does,so I bought another just like it with a 1.6 gig. I should have mentioned before the box has a reset button,but it wont restart the board. I think I've got the latest bios for it,if not it's easy to find. I'll post back later and let you know what happened.

 

That may, somehow, have a link to the problem. Recheck that the reset button wiring is connected to the correct pins. You can swap the connections of the reset button and the power-on button, their roles should be reversed.

Naaa, I double checked the pin-outs for power and reset. You right in saying their roles reverse,but it still wont work. The reset button shuts down the board but it doesn't restart. The bios up-date was a no go as well. I managed to download the wrong bios and ended up with nothing when I started it. Luckily,as I mentioned before,I have another exact mobo. I swapped the chips to get it started again,then hot swapped them so I could reprogram the bios(with the correct file this time). No change on the reset problem. I'm still looking for ideas.

Thanks again for the help Matt

 

Ahhhh! Hot-swapping the CMOS chip...errr!...new one on me! ,but I would only look for that info if I needed it . Seems to have worked, well done . Be careful of the model numbers (and the revision numbers) .

There may be something wrong with that button, it may jamming or shorting. Disconnect that reset switch completely. The system will run without it. EDIT: I take it that the reset button is connected "as the power button" when this happens. If not, they swap roles OK (the power button acts the same as the reset button)?

I had a Shuttle motherboard a few years back that put me through bios hell. Got to be rather good at hot swapping although most computer savvy folks shiver at the thought of it. It just takes a steady hand and the words "I got to do it right this time or it'll never work" going through your head.
But anyway, The buttons are working fine. Both have momentary contact. I did swap them too just to see. I have the feeling I'm stuck with this,which is no big deal except lots of times I'll restart the machine and come back later only to find sitting there with black screen.

 

I would still go with it being a bios setting since you have verified the wiring. Look in advanced chipset features. Make sure ACPI / APM are enabled in the bios. Check the settings for restart on power failure.

 

Hi Pete, or Oshwyn,
I'm sorry I haven't been back. I just been so busy doing other things necessary to stay alive and well. I read you post and intend to try what you suggested. In the mean time,(if you can imagine this) I got a reply from Syntax suggesting I set up the mobo outside the case to insure there is nothing shorting on the backside of the motherboard. That sounded worth trying,but I still don't have time to do it right now. I'll get back to you later and let yall know if it helped at all. Your advice or theirs. I should be getting back to it soon.

Thanks All,
Mark
